The utility model discloses a chopping type energy-saving electromachining pulsed power supply. The chopping type energy-saving electromachining pulsed power supply comprises a second adjustable direct current power supply, a first adjustable direct current power supply, a master control single chip microcomputer, a stabilizer circuit, a first power switch tube, a second power switch tube, a first high voltage isolating diode, a second high voltage isolating diode, a pulse conversion and arcing driving circuit, a pulse conversion and chopping driving circuit, and a power supply adjusting control circuit. According to the chopping type energy-saving electromachining pulsed power supply disclosed by the utility model, a current-limiting resistor with high energy consumption is omitted, and the utilization rate of the pulsed power supply is increased; the chopping type energy-saving electromachining pulsed power supply is easy to perform arcing, has the self-adaptive voltage adjusting and pulse current parameter adjusting performances, and meanwhile can separately adjust the pulsed voltage, the pulse current, the pulse width and the pulse interval.
